Vortech Odd Sound

Replaced the belt on the supercharger today and am now getting an odd buzzing/humming sound. I am aware of the normal gear lash sound from the head unit, but this is a new sound on top of that. The belt on there now is very tight, maxing the tensioner at idle. Would a tight belt cause this humming/buzzing or what is the normal sound of a bearing going bad in the supercharger?
